Abstract/Contents:"Total N applied during the main summer fertilizing program for turf influenced the early green color return of Kentucky bluegrass (Poa pratensis L.) the following spring. Where inorganic N was the only source, there was a highly significant positive correlation between the total amount of N and the early green color return in the spring. The results were linear within the range test (0.83-2.41 kg/100 m2) actual and all treatments fell within the confidence limits. When two applications of organic N were used with one application of inorganic N, no trend was established within the range of 1.00-1.88 kg/100 m2. In these latter combinations, there was a response to varying amounts of inorganic N, but not with organic N. The high correlations and nature of the fit to the regression line would suggest a 'luxury uptake' of inorganic N and overwinter storage by the turfgrass similar to that reported in some woody plants. Since the plots receiving organic fertilizer went dormant early in the fall, such uptake is not likely and the early green color return would seem to be dependent on the bacterial release of N from the organic residues within the soil as the temperature increased."
